Does anyone know anything about disk based xbox DLC troubleshotting?

I wasn't sure where to post this. I know I'm super late on this but its bugging the crap out of me. I got the game of the year edition of Arkham city and installed all the dlc on the second disk but when I go to play, none of it shows up! Iv'e re-downloaded several times to no avail. I've had AC since it was released and was never able to download the catwoman pack for some reason. I had hoped that the GOTY edition would produce a better result. Nope. Does anyone know anything about disk based DLC?

Usually any problems like this are fixed after i restart the game. Did u try the Xbox forums at the official website? May have better luck getting help or finding the answer faster there.

I'd think so too but the problem has persisted for quite a while. I'll probably try those forums next. I just figured I'd see if any fellow Freaks had advice before I went and made an account on those forums. lol.
